Heater structure

Abstract

A heater structure includes a heating core, at least one heating tube and a temperature switch. The heating core has an inlet, an outlet and an inner space, in which the inlet, the outlet and the inner space can be integrated to form a channel. The heating core has a first lateral wall with a first thickness, and the first lateral wall has an installation portion with a second thickness, in which the first thickness is different to the second thickness. The heating tube providing the thermal energy contacts the heating core. The temperature switch contacting the installation portion is used to detect the temperature.

What is claimed is: 
     
         1 . A heater structure, comprising:
 a heating core, having an inlet, an outlet and an inner space, wherein the inlet, the outlet and the inner space are integrated in space to form a channel, a medium pathway be formed between the inlet and the outlet, the heating core further having a first lateral wall with a first thickness, the first lateral wall further having an installation portion with a second thickness different to the first thickness;   at least one heating tube for providing a thermal energy, the at least one heating tube contacting the heating core; and   a temperature switch for detecting a temperature, mounted at the installation portion.   
     
     
         2 . The heater structure of  claim 1 , wherein the installation portion is a thin-shell structure with a thickness equal to the second thickness, wherein the second thickness is smaller than the first thickness. 
     
     
         3 . The heater structure of  claim 1 , wherein the installation portion is consisted of a thin-shell structure and a protrusive block, the protrusive block having a top end at a position corresponding to the first lateral wall, the thin-shell structure having a third thickness, the protrusive block having a fourth thickness, a sum of the third thickness and the fourth thickness being equal to the second thickness. 
     
     
         4 . The heater structure of  claim 3 , wherein the top end is located inside the inner space. 
     
     
         5 . The heater structure of  claim 2 , wherein the temperature switch is located outside the heating core. 
     
     
         6 . The heater structure of  claim 3 , wherein the top end is located outside the heating core, and the temperature switch is mounted on the top end. 
     
     
         7 . The heater structure of  claim 3 , wherein a sum of the third thickness and the fourth thickness is not equal to the second thickness. 
     
     
         8 . The heater structure of  claim 1 , wherein the installation portion is consisted of the first lateral wall and a protrusive block, the protrusive block with a fifth thickness having a top end with respect to the first lateral wall, a sum of the first thickness and the fifth thickness being equal to the second thickness, the heating core having a a second lateral wall with respect to the first lateral wall, the second lateral wall having a hole, the top end protruding into the hole, the temperature switch being mounted on the top end, the protrusive block and the hole having a sealing member in between. 
     
     
         9 . The heater structure of  claim 1 , wherein a projection area of the installation portion covers a contact area of the temperature switch and the installation portion. 
     
     
         10 . The heater structure of  claim 3 , wherein a projection area of the installation portion covers another projection area of the protrusive block. 
     
     
         11 . The heater structure of  claim 1 , wherein the heating tube is helical. 
     
     
         12 . The heater structure of  claim 1 , wherein the medium pathway is a channel able to flow a fluid. 
     
     
         13 . The heater structure of  claim 2 , wherein a projection area of the installation portion is in the medium pathway. 
     
     
         14 . The heater structure of  claim 4 , wherein the protrusive block is irregularly shaped to have a cross section of a non-absolute-island type, the protrusive block and the heating core having communicative portions and non-communicative portions, a least cross section of the communicative portions being no more larger than a circular area of the non-communicative portions. 
     
     
         15 . The heater structure of  claim 4 , wherein the temperature switch is located outside the heating core. 
     
     
         16 . The heater structure of  claim 8 , wherein a projection area of the installation portion covers another projection area of the protrusive block. 
     
     
         17 . The heater structure of  claim 6 , wherein a projection area of the installation portion is in the medium pathway. 
     
     
         18 . The heater structure of  claim 6 , wherein the protrusive block is irregularly shaped to have a cross section of a non-absolute-island type, the protrusive block and the heating core having communicative portions and non-communicative portions, a least cross section of the communicative portions being no more larger than a circular area of the non-communicative portions.
